Narrated Sulaiman bin Harb:
"Hammad bin Salamah narrated to us, from Thabit, from Anas, that the Prophet (ﷺ) recited this Ayah: So when his Lord appeared to the mountain, He made it collapse to dust (7:143) - Hammad said: "Like this." Sulaiman held his thumb over the tip of his finger on the right hand (so that only the tip of one finger was protruding) - and he [the Prophet (ﷺ)] said: "So the mountain fainted. 'And Musa fell down unconscious.'"
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ، أَخْبَرَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَرَأَ هَذِهِ الآيَةَ ‏:‏ ‏(‏ فَلََمَّا تَجَلَّى رَبُّهُ لِلْجَبَلِ جَعَلَهُ دَكًّا ‏)‏ قَالَ حَمَّادٌ هَكَذَا وَأَمْسَكَ سُلَيْمَانُ بِطَرَفِ إِبْهَامِهِ عَلَى أَنْمُلَةِ إِصْبَعِهِ الْيُمْنَى قَالَ فَسَاخَ الْجَبَلُ ‏(‏ وخَرَّ مُوسَى صَعِقًا ‏)‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ صَحِيحٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ حَمَّادِ بْنِ سَلَمَةَ ‏.‏
